A new driving mechanism for direction-controlled motion of nano-scale objects is proposed, based on a model of stretching a graphene strip linked to a rigid base with linear springs of identical stiffness. We find that the potential energy difference induced by the strain gradient field in the graphene strip substrate can generate sufficient force to overcome the static and kinetic friction for...

In this paper, we study the effect of single Boron/Nitrogen impurityatom on electronic properties of a silicene nano flake. Our calculations are basedon density functional theory by using Gaussian package. Here, one Si atom insilicene nano flake substitutes with a Boron/Nitrogen atom. The results show thatsubstitution of one Si atom with single Boron/Nitrogen atom increases distanceof impurity ...

When mechanically exfoliated two-dimensional (2D) materials are used for device applications, their properties strongly depend on the geometry and number of layers present in the flake. In general, these properties cannot be modified once a device has been fabricated out of an exfoliated flake. In this work we present a novel nano-patterning method for 2D material based devices, Pulsed eBeam Ga...

Two kinds of Bi2Se3 nanostructures, 3D rose-like hierarchitectures and monodisperse nanospheres, have been synthesized through adjusting the supersaturation of the precursor solution. Noticeable hydrogen storage capacity, amounting to 185 mA h g-1, has been found for the 3D rose-like hierarchitectures, which arises from the special micro/nano-hierarchitectures with highly crystallized flake-sub...

The Zinc oxide nanoparticles were successfully synthesized using nitrate as the precursor and extract of Illicium verum was used reducing stabilizing agent. Synthesized particles in nano size characterizedby FT-IR, Ultraviolet-visible SEM & XRD techniques. formed confirmed zinc by UV- Visible, FT-IR spectroscopic data gave results regarding structure prepared nano-sized particles. According...

Recently, Exfoliated graphitic carbon nitride (E-gCN) has drawn significant interest in the field of energy generation and storage. In this study, exfoliated nanoflakes are synthesized by condensation followed ultrasonic exfoliation. The supercapative behavior is analyzed. Structural analyses confirm formation thiazine heptazine heterocycles. Scanning electron microscopy image shows flake-like ...

Herein, we demonstrate that an electrochemical surface treatment of Fe foil with simple pulse reverse electrodeposition (PRED) prior to thermal oxidation can substantially enhance the photoelectrochemical (PEC) stability and water splitting performance of Fe2O3/Fe photoanodes. Comprehensive structural (XRD, FESEM, and HRTEM), compositional (XPS depth profiling), and electrochemical (EIS and Mot...
